Catalyzing Clean Power
Fuel Cell Grade H2 from ammonia without using Palladium membrane

The crux of the technology is the invention of a mixed metal oxide catalyst which can remove trace ammonia impurity in hydrogen to the level of 0.1 ppm.
For generating fuel cell grade hydrogen from ammonia, first it is converted to H2 through a reaction called cracking. The cracking reaction because of thermodynamic reasons, leaves a trace amount of ammonia unconverted. Because ammonia even in trace amounts is a poison for PEMFC, a purification step is needed after the cracking step. Till now, an expensive and unreliable Pd-membrane based technology has been the way to clean the trace ammonia from the cracked product making H2 generation from ammonia unfeasible.
RenCat ammonia to H2 generation technology is here to change that and drastically reduce the price and accessibility of fuel cell power.
RenCat technology uses an inexpensive mixed metal oxide based catalyst to selectively oxidise the trace ammonia after the cracking step to generate a PEMFC quality H2. The patent pending catalyst brings ammonia concentration down to zero by selectively oxidising ammonia from the H2 containing stream via a process called selective ammonia oxidation (SAO).
Not only that , through extensive research in Rencat has replaced noble and expensive Ru by abundant and inexpensive FeNi alloy.
Because of the use of very inexpensive metal oxides and metal alloys as catalyst, the price of H2 generator will be at least an order of magnitude lower compared to Pd-membrane based system.
Significant de-risking already happened through GAP and PoC investment
Inexpensive and abundant metal-alloy catalyst for ammonia cracking
No Palladium membrane in the system so no stability or price concern
